(Percentage rise question)
A metal sphere of radius 5.0cm behaves like a perfect blackbody at an initial temperature of 600K. By what magnitude must its temperature be increased so that its total power output rises by 25%? Express your answer both as the final temperature and as ΔT above the initial temperature.
(a) Calculate the final absolute temperature required for the stated rise in power.
(b) Determine the temperature rise ΔT in kelvin.
